Description
Technical Field
The present invention relates to the field of public transportation. And more particularly, to a bus stop reporting method and system.
Background
At present, buses in many cities are also manually reported to a driver, and in order to make passengers get off in advance, the driver usually needs to manually press a stop reporting button while driving. The manual stop reporting mode can possibly generate a missing report condition, and even can generate a condition that a driver is distracted and then a traffic accident occurs.
With the development of electronic technology, coverage of mobile networks and higher informatization degree of vehicles, automatic station reporting systems are also becoming popular. The automatic stop reporting system can remind passengers to get off the vehicle in advance through the vehicle-mounted voice equipment or the vehicle-mounted display equipment when the vehicle arrives at the stop, and inform the passengers of the next stop through the vehicle-mounted voice equipment or the vehicle-mounted display equipment in advance after the vehicle leaves the stop, so that the driver does not need to participate in the driving of the vehicle, the occurrence probability of traffic accidents is reduced, and the sitting experience of the passengers is improved.
The existing automatic station reporting system generally needs to store the position information (usually longitude and latitude coordinates) of each station in an operation line in a vehicle-mounted terminal, and the coordinates can be stored in a memory of the vehicle-mounted terminal in advance or can be issued to the memory of the vehicle-mounted terminal by a remote server platform through a mobile network so as to realize remote updating of station data. The vehicle-mounted terminal is also provided with a positioning unit, and longitude and latitude coordinates of the vehicle can be obtained in real time.
In order to enable passengers to get ready for getting off in advance, a landing range, which may be called a fence, is usually set around a station, and the fence may be circular or rectangular or other shapes. The vehicle-mounted terminal acquires real-time longitude and latitude coordinates of the vehicle through the positioning unit, compares the real-time longitude and latitude coordinates with the longitude and latitude coordinates of the station of the operation line, and when the vehicle enters the entering range, the vehicle-mounted voice equipment can remind that the vehicle is ready for getting off in advance or can display prompt information about to arrive at the station through the vehicle-mounted display equipment (an LED screen or an LCD screen which is displayed in a rolling mode in the vehicle). Similarly, in order to inform passengers of the name of the next station in advance, an outbound range is set by taking the station as the center, the vehicle-mounted terminal compares the longitude and latitude coordinates of the vehicle with the longitude and latitude of the station of the operation line, and when the vehicle exits the outbound range, the vehicle-mounted voice device or the vehicle-mounted display device informs the passengers of the next station. In general, the range of the outbound is smaller than or equal to the range of the inbound (because the inbound requires the passengers to get off ready, the passengers need to move from the head to the tail to the middle, especially when the interior of the vehicle is crowded or a large amount of baggage is carried, the range of the inbound is larger, usually more than 100 meters, and the outbound requires reminding the next name, so that the passengers get off ready earlier, and meanwhile, the passengers sit down and stabilize as early as possible, thus guaranteeing the personal safety, and the range is smaller, usually about 30 meters.
Obviously, the accuracy of the identification of the entrance range of the vehicle and the identification of the exit range of the vehicle determines the accuracy of the stop reporting and also influences the riding experience of passengers.
As more and more vehicles are on the road, the road is crowded. Usually, a busy stop is common to the phenomenon of bus queuing and creeping into the stop. The positioning error of civil satellite positioning units, whether GPS or beidou, is usually 2 to 3 meters or even less (circular probability error CEP), but this is measured in open areas. In large cities where high buildings stand up and the overpass meander, weak positioning signals scatter back and forth between buildings, and larger positioning errors are brought by reflection. The principle of satellite positioning also determines that the longitude and latitude obtained by the vehicle-mounted terminal at the same place is not invariable, but continuously drifts under the static condition, and the positioning error is increased.
The above factors provide challenges for the discrimination of the vehicle entrance range and the discrimination of the vehicle exit range when the vehicle terminal automatically reports the stop. By simply calculating whether the distance between the real-time longitude and latitude coordinates and the longitude and latitude coordinates of the station is within the inbound range or outside the outbound range, a high misjudgment rate exists, and in the following description, for simplicity of description of the problem, it is assumed that the inbound range and the outbound range are the same and are both 100 meters.
As shown in fig. 1, assuming that the vehicle slowly moves to the destination stop in the arrow direction in fig. 1 due to traffic congestion, if the bus stops near the point a in the figure when the bus moves to the stop represented by the point B, the distance from the point B is smaller than the entering range R according to the conventional determination method because the latitude and longitude coordinate shift is relatively large in the case that the bus is stationary i When it is determined that the vehicle is at the stop (the distance between the points A and B in FIG. 1), the distance from the point B is greater than the range R o (the distance between points B-C in fig. 1) is determined to be outbound. This is easily the case when: because of the offset of the position information of satellite positioning, the distance between the vehicle and the point B is smaller than the range R of the station i The vehicle goes into the station to report the station, and in the next second, the distance between the vehicle and the point B is larger than the range R of the station because of the offset of the position information of the satellite positioning o The vehicles go out to report the stop, at this time, the judgment of the coming in and going out of the stop of the vehicles is obviously wrong, and the wrong coming in and going out to report the stop can also cause overlapping of continuous twice report information, so that passengers are confused.
Therefore, it is desirable to provide a bus stop reporting method and system that can eliminate the influence of satellite positioning errors on stop reporting accuracy.

Detailed Description
In order to more clearly illustrate the present invention, the present invention will be further described with reference to preferred embodiments and the accompanying drawings. Like parts in the drawings are denoted by the same reference numerals. It is to be understood by persons skilled in the art that the following detailed description is illustrative and not restrictive, and that this invention is not limited to the details given herein.
As shown in fig. 2 and fig. 3 together, the present embodiment provides a bus stop reporting method, including:
acquiring current position information of a bus through satellite positioning;
judging the current distance between the bus and a stop according to the current position information of the bus and the preset stop position information on the bus line:
when the current distance between the bus and a certain station (the station is represented by a point B in fig. 3) is smaller than a station entering threshold value (the distance of the point A-B in fig. 3) and a first station entering identification aiming at the station does not exist, station entering report is carried out aiming at the station and the first station entering identification aiming at the station is marked;
marking a second inbound identifier for the station when the current distance of the bus from the station is less than an auxiliary threshold (distance at points B-D in fig. 3);
when the current distance between the bus and the station is greater than an outbound threshold value (the distance between the points B-E in fig. 3) and the first inbound identifier and the second inbound identifier for the station exist, outbound report is carried out for the station and the second inbound identifier for the station is cleared;
the inbound threshold is greater than or equal to the outbound threshold, the outbound threshold is greater than the aiding threshold, and the aiding threshold is greater than the satellite positioning error. In the implementation, the value range of the inbound threshold is 100-150m, the value range of the auxiliary threshold is 10-15m, and the value range of the outbound threshold is 30-120m. Since the satellite positioning error is usually smaller than 10m (between 2 and 8 m), setting the value range of the auxiliary threshold to 10 to 15m (i.e., the auxiliary threshold is larger than the satellite positioning error) can avoid the situation that the bus actually enters the range defined by the auxiliary threshold and is not judged, and in addition, since the distance between the outbound threshold and the auxiliary threshold is also larger than the satellite positioning error, setting the value range of the auxiliary threshold to 10 to 15m can more strictly avoid the process of misjudging that the distance between the bus and the station is smaller than the auxiliary threshold due to the satellite positioning error, and can avoid the situation that the bus has entered the range defined by the auxiliary threshold when the bus does not enter the range defined by the outbound threshold.
The bus stop reporting method provided by the embodiment can realize by setting the auxiliary threshold value and two stop entering marks: first, only when the bus stops, when the current distance between the bus and the station is judged to be smaller than the stop-in threshold value, stop-in reporting is carried out, and as the stop-in reporting is carried out and the first stop-in identification aiming at the station is marked, and the second stop-in identification is only cleared and the first stop-in identification is not cleared at the same time of stop-out reporting, namely the first stop-in identification still exists, in the process of the bus stop-in and stop-out after the stop-in reporting aiming at the station, even if the current distance between the bus and the station is not larger than the stop-in threshold value, the stop-in reporting aiming at the unified station can not be carried out any more in error; and secondly, after the bus passes through the station (limited by a second incoming station identifier), the bus stops when the current distance between the bus and the station is larger than the outgoing threshold value, and the second incoming station identifier for the station is cleared while the outgoing stop is reported, so that the repeated outgoing stop report for the unified station is avoided. It should be noted that, if the start condition of the incoming report is "when the current distance between the bus and a certain station is less than the incoming threshold and there is no first incoming identifier for the station", but the mode of limiting the incoming report and the outgoing report for a station to be performed only once, or the start condition of the incoming report is "when the current distance between the bus and a certain station is less than the incoming threshold and no incoming report for the station is performed", even the mode of recording the sequence of the stations is combined, the incoming report for the same station can be performed without error or repetition.
In summary, the bus stop reporting method provided by the embodiment can realize high-precision stop entering and exiting judgment, so as to realize accurate and timely stop reporting, and specifically comprises the following steps:
as described above, the starting conditions for the inbound and outbound reports in this embodiment are no longer that the simple distance of the bus from the station is smaller than the inbound threshold (or inbound range) and larger than the outbound threshold (or outbound range), but the following conditions are required to be satisfied:
conditions to be met for starting an inbound report:
the current distance between the first bus and the station is smaller than the threshold value of the station;
second, there is no first inbound identification for the station (this condition may indicate that an inbound report for the station is not made).
Conditions to be met for initiating outbound reporting:
the current distance between the first bus and the station is greater than the threshold value of the station;
secondly, the buses report the arrival of the station for the station, and a first arrival identifier exists;
third, the distance between the bus and the stop is smaller than the auxiliary threshold value, namely, the bus enters the range which takes the stop as the center and is limited by the auxiliary threshold value, and a second stop-in mark exists, so that the second stop-in mark represents that the bus passes the stop.
As shown in fig. 3, if the bus runs slowly near the point a due to congestion and other reasons during the process of running in the arrow direction to the station, when the current distance between the bus and the station represented by the point B is smaller than the arrival threshold value, the first arrival identifier for the station represented by the point B does not exist, and according to the starting condition for performing the arrival report, at this time, the station represented by the point B is subjected to the arrival report and the first arrival identifier for the station represented by the point B is marked; at the next moment, the current distance between the bus and the station represented by the point B may be greater than the outbound threshold value (particularly for the case that the inbound threshold value and the outbound threshold value are similar) due to the influence of satellite positioning errors such as drift, but since the vehicle does not enter the range limited by the auxiliary threshold value, a second inbound identifier for the station represented by the point B does not exist, and the outbound report for the station represented by the point B is not performed according to the starting condition for performing the outbound report; in addition, because the first arrival mark is marked, namely the first arrival mark is marked to exist, repeated arrival reporting is not performed when the bus runs between the point A and the point B and runs to the point B;
after the bus runs through the point D, marking a second arrival identifier for the station represented by the point B because the distance between the bus and the station represented by the point B is smaller than an auxiliary threshold value; however, at this time, the distance between the bus and the station represented by the point B is smaller than the outbound threshold value, and the outbound report for the station represented by the point B is not performed according to the starting condition for outbound report;
when the bus runs through the E point, the distance between the bus and the station represented by the B point is larger than an outbound threshold value, and the first inbound identifier and the second inbound identifier are also already existing at the moment, according to the starting condition for outbound reporting, outbound reporting is carried out for the station represented by the B point, and the second inbound identifier for the station represented by the B point is cleared;
when the bus runs between the point E and the vicinity of the point F, the second arrival mark is cleared, and repeated outbound station reporting is not performed any more; in addition, because the first arrival mark is marked, namely the first arrival mark is marked to exist, when the bus runs between the point B and the point F, the wrong arrival report is not performed.
In specific implementation, it can be understood by those skilled in the art that after the bus runs through a complete preset bus route, i.e. after the bus reaches the destination, the driver or staff should clear the first arrival identifiers of all the stops on the bus route, so as to avoid the situation that the bus does not enter for reporting when running again. The more preferred way of automation provided by this embodiment is: and when the current distance between the bus and the terminal point on the bus line is smaller than the auxiliary threshold value, clearing the first arrival identifiers of all stations on the bus line.
In particular embodiments, the reporting is performed by voice and/or display. Specifically, for the stop-entering report, when the current distance between the bus and a certain stop is smaller than the stop-entering threshold and the first stop-entering mark for the stop does not exist, the voice information of 'about to arrive at the XXX stop, please the passenger to get off' is played by using the vehicle-mounted voice player for one to three times, or the text information of 'about to arrive at the XXX stop, please the passenger to get off' is displayed in a rolling way by using the vehicle-mounted display device, and the modes of the voice report and the display report can be adopted simultaneously; for outbound station reporting, the optional way is to play voice information such as "the vehicle has driven away from the XXX station" once by using the vehicle-mounted voice player or to scroll display the display station of text information such as "the vehicle has driven away from the XXX station" by using the vehicle-mounted display device when the current distance between the bus and the station is greater than the outbound threshold and the first inbound identifier and the second inbound identifier for the station exist, and the voice station reporting and the display station reporting can be adopted simultaneously.
In specific implementation, the satellite positioning is GPS satellite positioning or Beidou satellite positioning, namely, the current position information of the bus can be obtained through GPS satellite positioning, and the current position information of the bus can also be obtained through Beidou satellite positioning.
